RADIATOR.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed .Tune 8.1907. Serial No. 377,913.

To uit' whom. it 'may concern: I l Be it known that I, GEORGE Hon'eijoN, si citizen of the United States, residing at \\"ilkinsburg, in thejcounty of Allegheny and Sto-tc ot Pennsylvania, have invented certain new and uscl'ul improvements in Radiators, ot' which the following is a specitiei'ition.

. .Uy invention relates to radiators, and its an electric current; to provide a radiator ol -the ,elec-tric type in which the heating coils lare subjected to the action of a current of water, thereby greatly increasing their capacity and presenting ,an increased radiating surface; to provide an electric radiator which will be free from unpleasant odors ordinarily arising from radiators of this type when 'operated at a high tension; t o provide. an

Velectric radiator in which any number of heating coilsmay be used to vary the capacity as4 desired and one in which all danger of short circuiting 1s avoided and in which the coils may be readily removed or replaced at any desired time without necessitating the removal of theradiator or taking it apart. These objects and others which will hereinafter appear, I attain by means ot the construction illustrated in preferred form in the accompanying drawings, wherein-A AFigure 1 is a side elevation, partly in scc- 'tion,` `of oneform of radiatorcmbodying my improvements, and adapted for use in connection with an'elec-tric current.;

EFigure?. is a front elevation of the same, with one-halfof the. electric. heater cover removed for the purpose ol' illustration, and

Figure 3 is a` horizontal section on :m enlarged scale, taken on thc line. Il I--l ll ol Figure i, through the. electric. heater and one ot the radiator columns. n

While my improvements are equally upp'icable lo radiators in general, have in the accompanying drawingsshown them in connection with a standard radiator consislin;r ol' a plurality'ol" four column sections Ll,"con nected :it ihc top and bottom by menus ol' the usual nipple joints 5. in-such u manner as t0 permit a current oi luid to circulate through the entire apparatus. The columns forming one ol' the end sections terminate at their lower ends in a box or cosine; 6 which is divided in' two compartments, not cong nected, by means of a wall or partition 7.

The inner of said compartments 8 is in eommumcation with the radiator columns. and is provided at its lower end with :i nipple connection l() b v means ol' which il may be connected'to the inlet pipes ot o hcatin.;r system when-it is desired to use the radiator in this manner, but when the radiator is intended tor use as a portable heater, i. c. when :i body ot water is inc-losed therein and heated by means of an electric current in :1 manner to be presently described, thev opeuin;r l() is closed by means'ot n threadcd plug 11, as illustrated in Figures 1 and 2, .lhe section :it the other end ol the radiator is providrd with the usual outlet connection i2 which is either connected lo n. discharge pipe, .when the radiator is used in connection with a system of piping, or to a compresion chamber i3 when such system of pipingr is dispensed with and a body of-water is contained iii the. heater as illustrated. in the drawings.

The outer compartment. 9 of the box 6, is provided with a removable cover 1.4, and is adapted to receive an electrical heater ot any preferred construction, lsuch for instance as that shown in the drawings, which consists ol' o. series of 'coils 15 embedded in pdrceln-in or some. other suitable material and controlled by means of an electrical switch 16 which muy be located upon the. cover 14 as illustrated in the drawings, or any other convenient point. Vhile I do not limit myself to :my one l'orm of electrical heater, I prefer to construct the same. in accordance with the drawings wherein the dividing wall 7 is provided 'with :t series oi` grooves'or corrugations 17 us illustrated in. Figure 3 for the reception of the porcelain covered coils l5, und in order that the coils may be readily re.- phiced or removed and the capacity of the heater thereby iin-reused or diminished proportionally to the number of radiator sections employed, l prefer to construct the coils in units ol one, two'(ns shown in the drawings), or m'orc coils each. .lo insure a .greater amount ol radiation oi hout through the wollv 7, u hiver ol. :isbcstospfsoui other non-conductor 1S, is phiccd between the coils und thc. cover 14. The radiator is further provided with the usual automatic air vulve. it) ot :my preferred construction,

From thtl torcgoing it will be seen that my improved radiator may be used in connection wit-,h a steam or hot water heating system by making the usual pipe connections at l0 and 12, in which case the coils 1.5 may be dispensed with entirely, or it so desired, the electric heater may be used in connection with a hot-water system by simply connecting the coils 15 t-o some suitable source oi" supply, in which case the temperature of the water will be raised during its passage 'through the box 6.

When it is desired to use electricityr alone as a source of heat, no pipe connections are necessary, tlie opening 10 in this instance being closed bv means of the plug 11, while a compression chamber or tube 13 is connect-ed at' its lower end to the radiator' at l2. The radiator is approximately filled with water through the opening at the top in which the Valve 19 is tapped', and the valve is then replaced. Water will be prevented from rising to any great height in the tube 13, by reason of the compression of the air therein, and it will be seen that when the water is heated it will expand into the tube 13 and it will result in a continuous circulation ofthe Water through the columns-4 and heating chamber 6 wien the device is in operation.

It will thus be seen that my device may bc used in connection with eitherastcain, hot.- Water, or electric system of heating without necessitating any change in its construction as it comes hom the factory, and when once installed it may be readily changed from one system to the other if desired, with a minimum amount of labor and at a trilling expense. Furthermore, when used as an elec,- tric radiator, it may be moved around as desired, and it will be noted in this connection that by reason of the cooling action of the water 'upon the heati coils their ca iat-.ity will be greatly increase( and a small electric heater constructed in connection with my invention will be equal in effect to one ot much larger size where no water is used. A

further' advantage of my device is that one size of section embodying the heater may be used in connection With any number of radiator sections, as its construction 'is such that it will be equally effective when but few coils are used1 in connection with a limited number of sections, as when the entire ity of-vertical pipes arranged side by side and communicating at 4their y:lower ends with a casing 6, a partition extending back into the casing and forming a compartment, and electrical heating means inthe compartment and a cover for the recess.

2. A radiator comprising a plurality of sets of columns 4, the end one of which is provided with a casing 6 provided with an inclosing partition 7 forming a compartment 9, electrical heating means in the compartment, and a cover for the compartment.

3. A radiator section comprising a vertical casing, a plurality of radiator pipes of substantially the thickness ofY the casing seated thereon and Acommunicating therewith, a partition extending back into the casing and forming a compartment, electrical heating means mounted therein and a cover for the compartment. l

4. A radiator section of substantially uniforni Width and thickness from top to bottom and comprising a vertical casing and a plurality of radiator pipes communicating with the end thereof, a corru ated 'partition extending 'backwardly into t forming a compartment, electrical heating coils mounted in the corrugations and a cover for the compartment.

5. A radiator section comprising in combination a' vertical radiator. column provided at its lower end with 'an inte v-al closed cas* ing, said casing being provide with an opening for the reception of a hot Water or steam pipe, and a recess adapted to receive an electric heater.

In testimony whereof I have hereunto signed` my `.name in the presence of the two su scribed witnesses.
